Counter and Trend

[Erwin van der Zwart]

You can create an event script which increases object value on each run. Trend will automatically show how many events happened during selected period. You can also get trend data from Lua to display certain stats: http://openrb.com/docs/

Code:

value = grp.getvalue('1/1/1')
grp.update('1/1/1', value + 1)

Tip: Use a 12. 4 byte unsigned integer object to have maximum size to count without exponent and also use:

value_reed = event.getvalue()
if value_reed == true then
    value = grp.getvalue('1/1/1')
     if value >= (256*256*256*256) then -- max of 12. 4 byte unsigned integer object
        grp.update('1/1/1', 0) -- reset object value to zero to start counting from start again
     else
        grp.update('1/1/1', value + 1)
   end
end

This makes the counting only happening on opening of the reed otherwise the count will happen on opening and closing, and will make the object value jump to 0 when max of object is reached.
